class_docstr: Keypoints class
  
  Parameters
  ----------
  pts : numpy.ndarray
      Key points as an numpy.ndarray in (x, y) format.
  height : int
      Height of the coordinate frame.
  width : int
      Width of the coordinate frame.
code: def __eq__(self, other):
      dim_equal = (self.height == other.height) and (
          self.width == other.width
      )
      data_equal = np.array_equal(self.data, other.data)
  
      return dim_equal and data_equal
